Most of the characters in UTY have so little connective threads between them that all you really need to do to justify shipping any two characters with each other is just having them in the same physical space, and since Dalv does move out into Snowdin, you could have Dalv and the shopkeeper somehow run into each other, and that satisfies that requirement.
Honestly, the relationships between the UTY characters kinda reminds me of the Z-fighters, where they get along with each other just fine, but unless something in particular happens that draws them together, they probably don't actually see each other too often, whereas the UT cast is (somehow) basically a family, though largely oriented around Frisk.
Unless Clover got resurrected after UT true pacifist, I could pretty easily see one or multiple of the UTY characters doing what Tien did at the end of the Cell saga and just going off and doing their own thing without ever expecting to run into the others again, the only ones who have a strong enough pre-existing connection are Starlo and Ceroba.
